Great Basin National Park is an American national park that was founded in 1986 and is situated in White Pine County in east-central Nevada, close to the Utah border. The most popular entrance to the park is via Nevada State Route 488, which connects to U.S. Routes 6 and 50 via Nevada State Route 487 via the nearby tiny town of Baker.
The dry, hilly area between the Sierra Nevada and the Wasatch Mountains that bears the name of the park is known as the Great Basin. This region is referred to as the Basin and Range Province topographically. The park, which protects 77,180 acres (31,230 ha), is situated about 290 miles (470 km) north of Las Vegas.
